The BP Rigby is tight, perfect bores, no buggered screws,and, with those 28 inch barrels, handles like a best 12 bore. I have not shot it yet but I am preparing to cast some 40 caliber pp projectiles out of an adjustable pp mould this weekend. It is my understanding that the 450-400 BP load was 255 grain bullet behind 110 grains black. I shoot black powder silouhette and schutzen for the last 15 years so I have experience loading black. If this load is not appropriate to my rifle I would appreciate input. The barrel flats tell me 400ex and it is also marked "Class D" It is also marked "Class D" on the rib right after Jn. Rigby, London. Do you have any idea what this means. Will have some pictures soon. Jeff at Rigby has my 450 cordite as he wanted to look at it and is putting on a gold bead front along with two extra strikers. Also sealing the mortises and tightening the screws. A really nice guy.

You are correct that the rifle came with 20 rounds of loaded ammo and dies. I will be pulling those 400 gain projectiles and dumping the powder this weekend. A friend just gave me 100 new Kynoch cases with two sealed boxes of 400 grain projectiles and 2000 Berdan primers (non-mecuric) for this case. I also received 15 rounds of cordite 450-400 with this group. I will save the projectiles and loaded rounds for when I purchase a cordite 450-400. I'm just having too much fun. My 450 3 1/4 cordite rifle is a honey. My friend sold me 75 rounds of original non-mecuric primed Kynoch ammo (both solids and softs) along with a plethora of brass and unopened Kynoch boxes of 480 grain projectiles. I took it to the range, having never fired a DR expecting some heavy recoil. Man, what a blast. I fired 14 rounds standing at a makeshift rest and my last two rounds were 1 inch apart horizontal. Most rounds were hitting 2 3/4 to 3 1/2 inches but I needed a solid rest todo better. The recoil was just a big push. I had more recoil from my 20 gauge. I'm hooked, sorry for the diatribe as I am not usually this noisy but no one to talk to here. Did have Superior make up 10 solids/10 softs to try out. Will let you know the results. Mike
